The league was converted from under-19 to under-20 and was expanded from 12 to 15 teams. Rangers left the league as a result of it entering liquidation at the end of the season to be replaced by Dundee which was promoted to the replace Rangers in the Premier League. In addition, the under-20 sides of the relegated Scottish Premier League club Dunfermline Athletic and the clubs finishing third and fourth in the Scottish Football League took up a place in the new league. A position in the league for teams outside the SPL was based on their youth academy's elite status.
